API Spec 11E Compliant Oilfield Pumping Unit Gear Reducer with Double Helical Gears and 20CrMnTi Alloy Steel

Oilfield Pumping Unit Gear Reducer (Gearbox)

This heavy-duty gear reducer is designed for beam pumping units in oilfield applications. It reduces the motor speed to drive the crank mechanism, converting rotary motion into reciprocating beam movement for oil extraction. It meets API Spec 11E standards and is built for long-term, high-load operation in harsh environments.

Parameter	Standard Range	Notes
Applicable Standard	API Spec 11E, SY/T 5044	Compliant with oilfield pumping unit standards
Model Series	JLH / CJH / API Standard (e.g., 320, 456, 640, 800, 1280)	Matches CYJ/CYJY pumping unit series
Rated Output Torque	6.5–89 kN·m (5,000–65,000 ft-lbs)	Depends on model (common: 9, 13, 18, 26, 37, 48 kN·m)
Transmission Ratio	25–35:1	Typical ratios for pumping units: 31.73, 30.56, 29.3
Input Speed	750–1500 RPM	Matches standard electric motor speeds
Output Speed	20–60 RPM	Adjusts pumping unit stroke frequency
Gear Type	Double helical (herringbone) or helical gears	Smooth, high-efficiency power transmission
Gear Material	20CrMnTi alloy steel, case-hardened	Surface hardness: HRC 58–62
Housing Material	Cast iron (HT200/HT250)	High rigidity and vibration resistance
Lubrication	Splash lubrication with gear oil (ISO VG 150/220)	Oil bath system for continuous gear lubrication
Brake Type	Band brake / shoe brake	For controlled stopping and holding under load
Operating Temperature	-40°C ~ +55°C	Adaptable to extreme oilfield climates
Mounting Style	Horizontal base-mounted	Compatible with standard pumping unit frames

Working Principle

1. Power Input: The electric motor drives the reducer input shaft via a V-belt pulley.

2. Speed Reduction: Multiple stages of helical gears reduce the input speed while multiplying torque.

3. Torque Output: The low-speed, high-torque output shaft drives the pumping unit crank.

4. Motion Conversion: The crank converts rotary motion into reciprocating beam movement, powering the sucker rod string.
